APPLICATIO S I FOR ATIO
This model (Figure 6) is being supplied to LTC users as an
aid to low frequency AC circuit design, but its use is not
suggested as a replacement for breadboarding. Simula-
tion should be used as a supplement to traditional lab
testing.
Users should note very carefully the following factors
regarding this model: Model performance in general will
